The probability is 1/16 that a gamete will receive only paternal chromosomes. In life
cycles that alternate between haploid and diploid stages, fertilization doubles
the number of chromosomes per cell, The pairing of chromosomes along
their lengths , which is essential for crossing over is referred to as synapsis
Answer: DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans. Like DNA, RNA is made up of nucleotides. ... There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Answer:
a.genetic code in the nucleus- DNA
b. main component in a ribosome- rRNA
c. translated with introns removed- mRNA
d. attached to amino acids -tRNA
e. translated including introns- pre-mRNA
Explanation:
a. DNA- is a nucleic acid molecule that acts as a genetic material in the organisms. In eukaryotes, the DNA molecule is present in the nucleus of the cell
.
b. rRNA- is a molecule formed by the transcription but does not undergo translation and is directly involved in the formation of the ribosome structure which provides the site for the protein synthesis.
c. mRNA- is the RNA formed from the DNA by transcription which contains the message for the formation of the protein molecule. The mRNA is formed after the modification like splicing which removes the non-coding sequence.
d. tRNA-transfer RNA is involved in the translation of mRNA as it brings a specific amino acid to the peptide after it recognizes the codon.
e. pre-mRNA- is the mRNA molecule that has not undergone any modification and thus contains the non-coding sequence also.
Answer:
Explanation:
First, recall the base pairs in DNA:
- Adenine and Thymine
- Cytosine and Guanine
We know this strand of DNA has 10% adenine. Since A and T pair, there must also be 10% guanine.
So, A and T make up 20% of the DNA strand.
That leaves 80% for cytosine <em>and</em> guanine. They are pairs, so they share this percentage equally.
There must be 40% cytosine and 40% guanine.
The strand of DNA has <u>40% cytosine</u>
