AUGGCGUUU which of the following DNA strands could have been the template for this RNA?

Delvig [45]

Answer:

3' TACCGCAAA 5'

Explanation:

Transcription is the process by which a particular DNA sequence (e.g., a gene) is used as a template to synthesize a complementary RNA sequence that grows in a 5′ → 3′ direction. This RNA molecule is usually a messenger RNA (mRNA) which is then used to synthesize a polypeptide chain (i.e., a protein) by a process called translation. The complementary RNA molecule produced during transcription is synthesized according to the base pair rules, i.e., Adenine (A) bases always pair with Thymine (T) bases, while Guanine (G) bases always pairs with Cytosine (C) bases. In RNA, Uracil (U) bases pair with adenine, thereby replacing thymines during transcription.

Which characteristics can be used to classify the tree as a gymnosperm rather than “any other type of seed” plant?

erica [24]

1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.

Can somebody give me the answer for these...

labwork [276]

Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis ploidy of cell become half

Means diploid cell form haploid cells

And 4 haploid daughters cells are formed.

In mitosis, ploidy of cell remain same

Means haploid form haploid and diploid form diploid.

1 cell form 2 daughter cells.

Hope this helps you.. Frnd ❤️
