Why can chromosomes be described as units of linked genes

Biology

Mrac [35]3 years ago

Answer:

Genes that are located on the same chromosome and that tend to be inherited together are called linked genes because the DNA sequence containing the genes is passed along as a unit during meiosis unless they are separated by crossing over.

A standard PCR cycle includes three steps: denaturation (95°C), annealing (55°C), and elongation (65°C).
xz_007 [3.2K]

Answer:

Denaturation process: The DNA template  

Annealing process: Primers  

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.

6. Why does meiosis increase genetic variation in the offspring, but mitosis does not? (1 point)
brilliants [131]
Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.

If the DNA nucleotides read 3'-ATG-CGT-GAC-5', the amino acid sequence of the resulting polypeptide
Marat540 [252]

Answer:

5’ – TAC-GCA-CTG-3’

Explanation:

As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.  

Purines include adenine (A) and cytosine (C)

Pyrimidine include thymine (T) and guanine (G)

Thus an A always pair with T and C always pair with G

Thus, the resulting poly peptide for the given amino acid sequence is  

3'-ATG-CGT-GAC-5'

5’ – TAC-GCA-CTG-3’
